Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480062, here are decompositions:

13 + 31480049 = 31480062
41 + 31480021 = 31480062
43 + 31480019 = 31480062
101 + 31479961 = 31480062
113 + 31479949 = 31480062
181 + 31479881 = 31480062
233 + 31479829 = 31480062
241 + 31479821 = 31480062

Showing the first eight; more decompositions exist.
